Two reasons if you must know. One: There are no pages using the redirect and therefore it is no longer needed. Two: This redirect serves no purpose as a separate name for the characters (like how CeCe Drake is also known as Charlotte DiLaurentis), the only difference is the and/&.
I wish someone would just tell the world about this decades ago, that way there would no confusion surrounding it. I'm sorry but nobody even complained about this naming ampersand thing. People including myself seem to be ok with certain corresponding names like Biff Tannen's Pleasure Paradise Casino & Hotel.
This is bad, right?
You might wanna notify admin Balthus Dire about this right away. He's big on ampersand I think.
That's ok. & thank you, sir. My apologies for this. It's just I never had any problem with the ampersand symbol in my words & my talks all my life, let alone in my editing of certain pages' names. Not once.
